Rikei ga Koi ni Ochita no de Shoumei shitemita. Temporada 2 Episódio 6

Yukimura is working hard on his computer, as usual, when Himuro suddenly says, I am in love with you. Her confession greatly shakes Yukimura. Unlike the last time, Himuro states her feelings matter-of-factly. Yukimura asks, What theory did you use to determine that you love me? Himuro replies by taking Yukimura out on a date and begins performing experiments theyve done before such as measuring heart rates, using an emotion counter, collecting saliva, and the kiss experiment.
